Underdog Sportsbook Promo Code WRALNC: Unlock first-bet mulligan worth up to $1,000

After sports betting officially went live in the Tar Heel State on Monday, March 11, there are plenty of reasons to get in on the fun. And by using Underdog Sportsbook Promo Code WRALNC today, you can unlock a first-bet mulligan of up to $1,000.

Users who sign up for Underdog's first foray into the sports betting world can expect a similar top-of-the-line experience. The folks at Underdog wouldn't have it any other way.

Here's how to sign up today to claim your $1,000 first-bet mulligan:

The biggest difference between Underdog Sportsbook and a more traditional book (like, say, FanDuel or DraftKings) is that Underdog will use bet multipliers rather than traditional odds.

Let's say North Carolina and Duke are squaring off in the ACC Tournament final in a few short days (it's not out of the question, as the Tar Heels are the 1-seed and the Blue Devils are the 2-seed). That should be a close game, right?

Well, perhaps a bet on the Blue Devils to win would be a .85x multiplier and a bet on the Tar Heels to win would be a 1.15x multiplier, implying that the Blue Devils are narrow favorites.

DFS players are quite familiar with pick'em options having multipliers like that. Now sports bettors will get to experience that fun and unique way of seeing their bet slips take shape.

And by signing up today, new Underdog Sportsbook users in North Carolina will receive a first-bet mulligan of up to $1,000. That means when you place your first wager (up to $1,000), you'll receive bonus bets back in your account equal to your initial wager if it loses. Basically, Underdog is giving you 2 tries to win your first bet. Not bad.
